The WRRA committee has decided to remove the allowance for non-rotating wheel enclosures in the Un-Faired classification. This decision was made after recommendation and consultation with a number of key organizers and racers in the US and in Europe.

Unfaired Recumbent:
An unfaired recumbent has any number of wheels in any configuration or length.

The vehicle construction shall be such that its shape does not overtly direct airflow around the rider's body, nor attempt to reattach the airflow behind the rider by use of tail fairing devices. The only exception being the use of an aerodynamic shaped helmet. The vehicle can incorporate aerodynamic
fairings to make its structure and components more aerodynamic. Allowed fairings are: rotating wheel covers and splitter plates.

Well if it wasn't there would some unhappy NoCom record holders here?

Alan,
Isn't John's bike that he built for you legal for stock? If its not legal, than a NoCom might not be either. Its chainstays are a bit larger than a noCom and much more stiff. They are no where near large enough to qualify as a tailfariing.

Alan,
Listed below are the HPRA Stock Class HPRA rules. These have not changed. Wheel covers are still allowed. I will look forward to seeing you demonstrate the superior construction and performance of your vehicle at HPRA races and Local TT's.

HPRA Racing Classes

STOCK
Vehicles in this class may have any number of wheels. Vehicle/frame design may not incorporate any form of fairing which is not an integral part of the frame. Specifically, brazed on, welded on, or epoxied on integral parts of the frame which do not divert airflow around the rider are allowed. Wheel discs/covers are allowed. Supplied number plates do not constitute a fairing. Rider is male or female of any age.
